I stayed at the apartment for 1 week while in Bangkok. The apartment was nice and self-contained. the building has an amazing pool and gym, and a shuttle van to public transport (although it is also within walking distance). I recommend taxi to get to the apartment from the airport, as I took the train and it is quite difficult with luggage to get from the station.
The building is in the up-and-coming area of Bangkok, which has great street food and restaurants and coffee shops within a 1km radius of the building.
